Nearly 100,000 Canadians signed up to become organ donors after learning a victim of last month's Humboldt Broncos bus crash had signed a donor card just weeks before the crash, and wound up saving six lives.

Canadian Blood Services reports there were 99,742 registrations in April alone, and that number only includes provinces that have online registration: British Columbia, Alberta, Manitoba, Ontario, Quebec, and Prince Edward Island.

The other provinces reported receiving a lot of phone calls from people inquiring about how to register.

Spokeswoman Jenny Ryan calls it an extraordinary show of support for organ and tissue donation and says the tragedy inspired people to be more aware.

Logan Boulet signed a donor card after his 21st birthday, several weeks before the bus carrying him and the rest of the Humboldt Broncos hockey team collided with a tractor trailer in rural Saskatchewan.

He was among the 16 people killed in the crash.

The president of Ontario's organ and tissue donation agency says there are typically 42 online organ donation registrations a day, but since the tragedy that number has jumped to almost 800 registrations per day.

Ronnie Gavsie says the bus crash jolted people out of their complacency and got them to register as donors.
